Elective Days are an event in Hatoful Boyfriend, in which the protagonist can add points to either Wisdom, Vitality or Charisma. The player may gain five points at a time by participating in one of three classes (which they may choose).
Math class boosts wisdom, which will help do better on tests. Gym class helps them get more Vitality. Music class increases their Charisma. These happen nine times in the course of a full three-semester game to the end, for a maximum of forty-five points in any category.
- They player will already start at the top of the entire school in terms of Vitality, due to being over five feet tall with 800 points.
